Comet 17P Holmes and the California Nebula in Stereo
I've posted an animation below, 29 Amphrite is also in the frame, but it's hard to see in the Google Video, you are going to have to download the avi (1.1 Mb) from here, and then run it at 2x magnification to see this asteroid easily. Just below Amphrite is what appears to be another asteroid, but nothing appears on my star maps. An artefact or a real unknown object? (update: Comet Al has identified this as 46P/ Wirtanen) 1 Ceres was also clearly visible, but is outside the area of this animation.
In making these images I've just updated ImageJ to version 1.39u, and it rocks! Finally got the Z profiler to work, and the Astrometry program is sort of working, so I will have another go at exoplanets real soon.
Nice work. The extra asteroid, traveling up and to the left . I think this is Comet 46P/Wirtanen.
I am very sure it is, It and holmes have faded from the FOV now.
I can't detect C/2008 C1 Chen Goa which is crossing the FOV now, mag 11
